I quote from the PR log:

gnu make 3.81 -> 3.82 is, sadly, exceptionally non-trivial. A number of
features present in releases prior to 3.82 are technically "wrong", and
this release has corrected them. A _lot_ of stuff breaks. It will be
looked at, but don't hold your breath.
Plenty of other stuff was happening in autotools-land at the time. We had already run a previous preliminary analysis of gmake 3.81->3.82 and it was _not_ pretty.
That update to the PR took just a little under 2 hours from initial submission. Suggesting that it took until March 11th is disingenuous at _best_

This requires multiple -exp runs. A number of ports that failed with 3.81->3.82 have a non-trivial number of ports that depend on them. Simply taking the first set of breakage does _not_ present the entire picture. Short term hacks, such as allowing those ports to build with 3.81 are _required_ in order to fully understand the depth of the situation.
Infrastructure work is a painful experience. Throwing out a PR with "exp-run probably desirable" is not particularly useful, and shows a certain naivety when it comes to such wide-ranging changes. It is a highly iterative procedure, requiring many man- and cpu-hours of work. Those of us that do it may not be doing the best possible job, but there's a distinct lack of volunteers to actually run the process. Behind closed doors, and in the Cabal Club, of course.
